## Norwegian Nynorsk
### Etymology

Uncertain, but etymologists have pointed to a couple of explanations. One proposes a derivation of Old Norse taufr (“sorcery, charms”), in reference to the practice of primitive magic in the area, reckoning Taufr to be a name of the creek running through. Another proposes a relationship with Old Norse taug (“string, rope”) and teygja (“to stretch out”), in reference to the nature of waterflow of said creek.
It was attested through the late medieval and early modern periods as a Taufer (1389), Taugir (1427), and af Thawgh (1463), Thow (1563), Touu (1567), Thouff (1602), Though (1606), Thoug (1610), Thov (1661), and Toug (1723). Another spelling, Tou, is still preserved in the name of a local brewery.
